Taw qhia
2,4-Difluorotoluene yog ib qho organic compound. Nws yog cov kua uas tsis muaj xim nrog cov ntxhiab tsw tshwj xeeb.
2,4-Difluorotoluene muaj ntau hom kev lag luam. Nws tseem tuaj yeem siv los ua cov txheej txheem ua haujlwm siab, dyes, resins, thiab surfactants.
Muaj ntau txoj hauv kev los npaj 2,4-difluorotoluene. Ib txoj kev npaj ntau yog tau los ntawm reacting toluene nrog hydrogen fluoride. Cov tshuaj tiv thaiv feem ntau tshwm sim nyob rau hauv cov roj theem, thiab nyob rau hauv qhov tsim nyog kub thiab siab tej yam kev mob, los ntawm qhov kev txiav txim ntawm ib tug catalyst, lub hydrogen atom ntawm lub benzene nplhaib nyob rau hauv lub toluene molecule yog hloov los ntawm ib tug fluorine atom los ua 2,4-difluorotoluene. .
Cov ntaub ntawv kev nyab xeeb ntawm 2,4-difluorotoluene: Nws yog cov kua nplaum uas tuaj yeem hlawv tau thaum raug nplaim taws lossis cua sov. Yuav tsum tau saib xyuas kom tsis txhob kis mus rau ntawm daim tawv nqaij, qhov muag, thiab ua pa thaum tuav lossis siv. Cov khib nyiab yuav tsum tau khaws cia kom zoo thiab pov tseg kom tsis txhob muaj kuab paug rau ib puag ncig. Thaum siv, nws yog ib qho tsim nyog yuav tsum ua raws li cov txheej txheem kev nyab xeeb ntawm kev ua haujlwm thiab kev tiv thaiv kev tiv thaiv kom muaj kev nyab xeeb ntawm tus kheej thiab ib puag ncig kev nyab xeeb.
